Several top AI firms have hired philosophers to address fundamentally philosophical questions arising at the frontier of AI development. The hires are concentrated at Anthropic, Google DeepMind, and OpenAI, spanning specializations from moral philosophy and decision theory to epistemology and the philosophy of mind. At Anthropic, Amanda Askell, who holds a PhD in philosophy from NYU and a BPhil from Oxford, leads the Personality Alignment team and is directly responsible for how Claude engages with users on sensitive topics. She has raised the possibility that future AI models might develop a form of “rational resentment.” Joe Carlsmith, who holds a DPhil in philosophy from Oxford, works on Claude’s constitution and character design and has argued that philosophical clarity is the binding constraint on alignment research. Ben Levinstein, a former tenured associate professor at the University of Illinois at Urbana-Champaign specializing in epistemology and decision theory, left his tenured position to join Anthropic full-time in late 2025 to focus on alignment research, including whether large language models have genuine beliefs.
